Cautions on system configuration

Pay attention to the following points in the power supply wiring (system design) so that erroneous inputs to or
outputs from remote I/O units can be prevented.

1 )

Countermeasures against erroneous inputs or outputs occurred when the power is turned on or off

•

When the power is turned on
[Draft 1]Turn on at first the power of remote I/O units and the power of master blocks supplied from the

outside. Then, turn on the power of a basic PC unit.

[Draft 2]Turn on at the same time the power of remote I/O units, the power of master blocks supplied

from the outside and the power of a basic PC unit.

•

When the power is turned off
[Draft 1]Turn off at first the power of a basic PC unit. Then, turn off the power of remote I/O units and the

power of master blocks supplied from the outside.

[Draft 2]Turn off at the same time the power of a basic PC unit , the power of remote I/O units and the

power of master blocks supplied from the outside.

2 )

Countermeasures against erroneous inputs occurred when the power of a remote I/O unit is instanta-
neously interrupted
If the power of a remote I/O unit is instantaneously interrupted, erroneous inputs may occur.

•

Causes of erroneous inputs by instantaneous power interruption
The hardware of a remote I/O unit converts the I/O unit power supply (24V DC) into 5V DC inside, then
uses it.
If the power of a remote I/O unit is instantaneously interrupted, the following relationship is generated.

(Time until 5V DC inside remote I/O unit is turned off)

>

(Response time of input unit ON

→

OFF)

Accordingly, if I/O refresh occurs within the time shown as

➀

in the figure below, erroneous inputs occur.
